Gemstones are naturally occurring, precious or semiprecious minerals that are valued for their beauty, rarity, and often, durability. These minerals are cut and polished to be used in jewelry or other decorative applications.
Gemstones can exhibit a range of colors, clarity, and brilliance, and they are often prized for their aesthetic qualities. Examples of gemstones include diamonds, rubies, sapphires, emeralds, and various types of quartz (such as amethyst and citrine), among others.
The value of a gemstone is influenced by factors such as color, clarity, cut, and carat weight, commonly referred to as the "Four Cs."
